Description

The present invention uses a plurality of LEDs each containing blue: yellow: red elements in one LED, makes one light as a display body (one unit), uses the light as a traffic signal, It relates to a traffic light with a single light direction arrow that performs the traffic control function with a single light by including a blue direction arrow when the inside of a circle turns red in three lights: blue: yellow: red .

In general, traffic lights are provided with three lights that turn on each of blue light color: yellow light color: red light color to indicate progress, slow speed, stop, etc. In addition, blue light color It is composed of multiple lights, such as with a light that displays a direction arrow that lights up at, even when using an LED as a light for such a traffic signal, one color light is turned on with one light the LED lights itself is a single source single light color, therefore, blue light: yellow light: when lit red light and required three lights, also under it, the light of the plurality of directional arrows Was attached.

As described above, in the conventional traffic signal device, a plurality of lights that respectively display blue light: yellow light: red light: blue direction arrows are provided, so that the weight of the traffic light itself is heavy. In addition, when one of these lights is lit and only a certain traveling direction is permitted, the permitted traveling direction when a plurality of lights are lit is not judged instantaneously. In some cases, it was difficult to discriminate due to reflection from sunlight.

Therefore, the present invention was devised as a result of repeated research to solve the problem, and uses a plurality of LED light emitters having a structure in which three light sources (elements) of blue: yellow: red are incorporated in one LED light emitter. In a traffic light with a single light indicator (one unit) , the light is continuously emitted in the order of blue-yellow-red colors by the operation of the relay timer. When the indicator turns red, a blue directional arrow can be displayed with a time lag.The directional arrow shares part of the light circle and is shown as a directional arrow protruding out of the circle. It can be shown in any direction, so that it functions as a single traffic light.

When a driver sees a light, the traffic control details can be judged instantly, and not only it will not be mistakenly reflected by the sunlight, but also the light can be made thin. The traffic light itself can be reduced in weight, and can be installed freely without requiring a lot of installation space .

An embodiment for carrying out the present invention will be described below with reference to the drawings. The LED 1 incorporates three light sources (elements) of a blue element 17: a yellow element 18: a red element 19 and has a negative electrode. Side cathode (K) foot 21:22:23 and electrode positive side anode (A) foot 24 were provided (see FIGS. 1 and 2).

  By combining a plurality of LEDs 1 configured in this way, a single light display body (one unit) is formed, and the display body itself becomes the light 3 in the traffic light 5. The outer shape of the main body is circular, and the LEDs 1 are arranged in a plurality of rows and columns in a row and row on the substrate. The blue direction arrow is a part of the circle of the light 3. The blue light direction arrow 4 is displayed by sharing and projecting out of the circle of the light 3 (see FIG. 6). The LED in the blue direction arrow is LED1 in the circle and the LED11 is in the circle outside. It was.

The explanation will be made from the anode and cathode of the electrode. The entire circle is composed of the LED 1, and the inside of the circle is the ground of the cathodes 21, 22 and 23 of the cathode (K) and the anode 24 of the anode (A) on the substrate. In addition, as shown in FIGS. 8 and 12, wirings 13, 14, and 15 connected to the cathode (K) are grounded to the back surface of the substrate. The directional arrow 4 portion is continuous from the inside of the light circle to the outside of the circle. The outer part of the arrow in the direction arrow 4 is an LED 11 composed of only a blue single light source element. The cathode (K) foot 20 and the anode (A) foot 25 are provided on the substrate. The wiring 12 that is grounded and connected to the cathode (K) and the wiring 16 that is connected to the anode (A) are grounded to the back surface of the substrate (see FIGS. 9 and 10). The wiring 16 is common to the LED 1 and the LED 11. Wiring.

The circuit of the relay timer has an electromagnetic relay electromagnetic contactor that is the main body of sequence control so that its operation can be clearly understood, and a diode for preventing a backflow of current is installed. Therefore, blue 13: yellow 14 : Red 15 are not conducted simultaneously with each other (see FIG. 14).

In order to sequentially and continuously emit the LEDs containing the elements of blue 17: yellow 18: red 19 in the built-in LED, blue to yellow to red are sequentially emitted by the action of the control circuit (relay timer) 2 ( The light of the traffic light is also controlled by the control (relay timer) 2a so as to emit light sequentially and sequentially from blue to yellow to red to the direction arrow (see FIG. 4). The time difference in which the blue / yellow / red / blue direction arrow changes is the blue dial 6 of the control circuit (relay timer) 6: yellow dial 7: red dial. 8: Adjustable with the blue arrow dial 9 (see FIGS. 4 and 11).

  The operation of the relay timer will be described. When the current is applied to the cathode (K) blue 13 (see FIG. 13), the traffic light lights up blue (see FIG. 14), and the current of the relay timer is the cathode (K). ) When activated on yellow 14 (see FIG. 15), traffic light lights on yellow (see FIG. 16), when relay timer current is activated on cathode (K) red 15 (see FIG. 17), traffic When the traffic light turns on red (see FIG. 18), when the relay timer current is activated on cathode (K) blue 12, 13 in the direction arrow, and simultaneously on cathode red 15 (see FIG. 19). The part where the arrow part is blue and the inside of the circle is red except for the arrow part (see FIG. 20). The part where the relay timer current operates in (K) blue in the arrow part and (K) red in the part in the circle. When shown separately, arrow When a current is applied to the cathodes (K) blue 12 and 13 (see FIG. 21), the traffic light lights display a blue direction arrow (see FIG. 22), and the relay timer current is the cathode in the circle ( K) When operating on red 15 (see FIG. 23), the inside of the circle is lit red except for the arrow (see FIG. 24).

The direction arrow will be described. The direction arrow is formed in the light 3 main body corresponding to the single direction of travel so that the direction of travel indicates the direction of travel, and the direction of travel is either straight forward: leftward: rightward When the direction of travel is indicated, the arrow-shaped portion is configured to rotate both inside and outside with the center axis of the circle as a base point (see FIG. 25). Is configured such that the arrow-shaped portion is rotated around the center axis of the circle (see FIG. 26), and the case after the configuration is shown in FIG.

Such an invention is considered to be excellent in industrial applicability.
